The main aim of the article is evaluation of investment processes in agriculture in Poland in 2000-2011. Tendencies in range of investment activity after 2000 should by favourably estimate. Essential improvement in this area has happened especially after integration with the EU, in relationship to possibilities of funding investments by union funds. Also the enlargement of integration investment activity in agriculture has been noticed on background of tendency in total economy. In spite an increasing tendency in case of ability to invest in agriculture, its level was insufficient to set – back decapitalization of fixed assets in the whole agriculture. The situation would be positive if the tendency of growth degree of consumption of assets was stopped. On the other hand, awareness is necessary of the considerable differentiation in relation to investment activity with regard to the scale of production. It can be supposed, that started investment processes will bring to a part of agricultural farms multiplied effects which will actively use the investment support under the CAP instruments and preferential credits. It will intensify the processes of polarization in agriculture.
